Janitor it is. She reads up.

"Lead the way." 

There's a pretty comprehensive section in the encyclopedia on stain removal, there's also a facilities section with some interesting information, including a description of types of teleporters and how to recognize them. Ones like the 'elevator' that they went through are listed as standard but there are also airlocks, trapdoors, and code-ring teleporters.

Riley goes back to reading about medical procedures. Whenever Maddie feels ready or is just bored there's a test she can take to see if she qualifies.

The next thicket of bushes and trees gives way to a clearing surrounded on all sides. In the middle is a hexagonal obelisk. On each side of the obelisk is a picture of a weird oblong pentagon with the same point marked near one corner. From there there is a meandering line leading to some other point within the pentagon, with various little short offshoots which seem to indicate turns you're not supposed to take. Below each diagram is a short line and then a shelf. From the side the came in on clockwise they read Stored power for travelling afield, an eye of glass and metal, a child's toy bouncing high, a weapon thin but strong, a wheel that turns and finally, a box for thoughts.

"Well, that's a scavenger hunt if I ever saw one."

When she's read everything there is to read cursorily, she'll take the test.

"This is the kind of thing we probably shouldn't be playing along with, but I'd hate to become predictable. Let's go." 

The test takes about twenty minutes and seems to delight in asking about silly minutia, with her cursory read she'll be able to answer about a third of the questions correctly, and at the end she's rated as Moderately Competent and that she's employed as a Janitor (Provisional). Her list of rights and privileges includes the ability to unlock doors in the black area. It notes that upon being judged competent she will be able to switch some areas to be cleaned exclusively by residents, change preferences on whether beds should be made by the cleaning robots, reactivate teleporters in her area, assign new access codes to teleporters, and conduct debugging tests on the various locking mechanisms in his area, and manage swimming pools and other similar facilities.

"The teleporters and the doors sound really useful, swimming might be nice too."

"I think I like it makes sense to follow one of these routes, but I don't want to leave Alice alone for too long." There's a thin garden path that matches the maps leading out of the clearing.

"Is there one area for each colored slip? When I came in, I saw six."

"She wouldn't follow us, would she? You know her better. We can report back."

"I think so, there are a lot black accents around here, and I haven't seen accents in the other five colors."

"Alice will stick to the plan unless we're gone for like an hour or two, but she'll worry before then."

"Did you find a map? Maybe even a conveniently labeled one?"

"We'll go back, tell her what we found so far, and take a break. Then we can come back here, and keep pushing until we find an edge."

"Well, there's a directory for a mall which I think is supposed to be below us. It's kinda insane though. The mall has 450 km of linear storefront. Even the closest other home complex is about 75 km from us if I've read it correctly. There are bike stores though."

"Alright, sounds reasonable." Zahn starts walking back the way they came.

"Have you checked it out? We should probably take a look and see what we can use." 

Back to Alice, then. 

"I've looked a bit at the directory and been downstairs to confirm it matches. I haven't made up a list of what stores specifically it makes sense to check out yet. Give the distance, I think the bike stores are something we should check early in the list, hopefully they'll have some way to haul cargo around."

For experimental purposes Alice stands back and lets them try to open the door. It works. "Welcome back, did you find anything interesting?"

"Makes sense. I'm going to take a look at the directory."

"Not really. I think we need to go further, but we decided to come back so you wouldn't stress too much. We can revisit it later."

"Alright, in case you haven't seen them we have a greenhouse, a games/arts and crafts room, a tv room, and a gym/dojo. Not sure if that'd affect your selections."

"I wasn't worried just yet, but thank you for your concern Zahn. Do you think it's safe enough for the three of us to go together when you go back out or should I wait here again? I might get a book from the library and a chair for lack of anything better to do if I'm going to be waiting for a while."

"We could split it in half, and each read a set number of entries? Skipping anything that we have covered. If there are other people, the most important thing is getting to them or signaling where we are somehow."
